PNW....This wx is typical during Turkey day week. We had many power outages onTurkey day from winds & lots of rain. What's different this year?

thats cuz the op probably doesnt live here. as a resident of vancouver/portland area its just a normal winter. a little rain wont stop me fromm hittin up the winterbrewfest so bring it on

Yes, PNW winter weather can be pretty alarming to people who live other places, but so far this storm has not delivered the water that a storm two or three years ago did.

Flooding and mudslides all up and down the coast shut off all ways in and out of Seattle (except by boat) for a couple of days. Even the railroads shut down because of the snow in the Cascades. It only lasted a couple of days until the airports opened, but still it was a mess if you wanted to go out of the Sound area.

Commuter trains were less fortunate. Mudslides canceled service on the Northline Sounder to Edmonds, Mukilteo and Everett, until at least Wednesday afternoon. And the Southline Sounder to the Green River Valley, Tacoma and Lakewood was likely to be delayed 15 to 20 minutes per trip, said a Sound Transit alert.

Today I learned, ARkStorm is now a book for "preppers" and there is a "PrepperStock."ARkStorm

The ARkStorm (for Atmospheric River 1000 Storm) has brought a devastating flood of biblical proportions to California forcing millions of people to evacuate. For the preppers attending PrepperStock this year the troubles brought about by the this disaster have just begun as the economy begins a s...Like · · Share · September 13 at 7:24am near Sacramento, CA

What happens when El Niño and La Niña take a break?November 19th, 2012 at 1:41 pm by Jim Spencer under Weather

(By Bob Henson – University Corporation for Atmospheric Research)

It’s official: NOAA has cancelled the El Niño Watch that was in effect since June (see PDF). But if you think this guarantees a placid U.S. winter, you might find yourself surprised.

El Niño and its counterpart, La Niña—together referred to as the El Niño/Southern Oscillation (ENSO)—shape seasonal climate across North America and elsewhere. They respectively warm and cool the surface waters of the eastern tropical Pacific, typically for a year or two at a time, which in turn triggers a chain of atmospheric responses around much of the globe. ENSO’s influence tends to grow during northern autumn and peak from around year’s end into northern winter.

i would also hazard a guess that we'll be seeing tornadoes hitting the midwest again by week's end, look at the temps in the southern/mid united states (VERY WARM), and forecast is for a severe blizzard in north/midwest by friday, same system as this one.

In Seattle, yesterday was a type of rain that off the hook! Traffic nightmares everywhere. It was a monsoon that dumped all day long! No let up at all. You couldn't see ten feet in front of you while driving.

Today is chill, gray clouds but no rain. The ripple clouds are here now though. We shall see.

at this point i'ma just sitting tight and waiting to see how those t-storms shape up later.

i don't see how this is not going to be clobbering the midwest very soon.

thanks again to luisport for the twitter links, this one popped up about 22 hours ago:ECMWF 12z in the long-range (+9 days) has a powerful blizzard for Great Lakes. We'll see if any ensemble agree pic.twitter.com/1r6Q87GFView photo

See... i told you weeks ago we could see 100 year flooding when someone posted what looked like a hurricane off of alaska and i told you specifically we should be concered about all that moisture just sitting there growing and throwing it our direction. And you said... flooding is common... it is but not when it swallows entire counties lady... 100 year flood...

reminder i started this thread with the intention of learning more about these anomalous weather patterns. i read weather more from the sky than i do technical terms, but finding the tech quite interesting.

A low pressure system, or "low," is an area where the atmospheric pressure is lower than that of the area surrounding it. Lows are usually associated with high winds, warm air, and atmospheric lifting. Because of this, lows normally produce clouds, precipitation, and other bad weather such as tropical storms and cyclones.

In addition, areas prone to low pressure do not have extreme diurnal (day vs. night) nor extreme seasonal temperatures because the clouds present over such areas reflect incoming solar radiation back into the atmosphere so they cannot warm as much during the day (or in the summer) and at night they act as a blanket, trapping heat below.

The USGS Multi Hazards Demonstration Project (MHDP)’s second full scenario, called ARkStorm, addresses massive U.S. West Coast storms analogous to those that devastated California in 1861–62. Storms of this magnitude are projected to become more frequent and intense as a result of climate change.

Atmospheric rivers are embedded within much broader atmospheric storms referred to technically as “extratropical cyclones” (ECs). ECs are the winter-time analogue to hurricanes, but have much different structure. Also, they gain their energy largely from the pole-to-equator temperature contrast, unlike hurricanes, which draw their energy from ocean surface heat content. ARs are the business end of ECs because where the AR hits the mountains it can create extreme precipitation, flooding and high winds. In terms of impacts, an AR is to the broader EC it is embedded within, as the hurricane eyewall is to the broader hurricane of which it is a part. The importance and structure of ARs has become recognized recently through new satellite data and field experiments.

The atmospheric mechanisms behind the storms of 1861-62 are unknown; however, the storms were likely the result of an intense atmospheric river, or a series of atmospheric rivers, striking the U.S. West Coast. With the right preconditions, just one intense atmospheric river hitting the Sierra Nevada mountain range east of Sacramento could bring devastation to the Central Valley of California. An independent panel wrote in October 2007 to California’s Department of Water Resources, “California’s Central Valley faces significant flood risks. Many experts feel that the Central Valley is the next big disaster waiting to happen. This fast-growing region in the country’s most populous state, the Central Valley encompasses the floodplains of two major rivers—the Sacramento and the San Joaquin—as well as additional rivers and tributaries that drain the Sierra Nevada. Expanding urban centers lie in floodplains where flooding could result in extensive loss of life and billions in damages.” [link to urbanearth.gps.caltech.edu]

Some sort of humming just started in Redmond. It sounded like it might be a street cleaning truck in the distance but I went out for a drive and I can hear it everywhere I go. Been going on for 20 minutes now.

Just to give the drylanders a little perspective..

Just to give you a little perspective... lived in skagit county of Washington state my whole life and we had 1/3 or more of our annual rainfall in February. This summer was the dryest on record even for washington... and this coming winter and spring will be the wettest. Flooding and droughts are always together if one comes first the second will show its ugly head sooner than later... and i think everyone knows the whole world experienced droughts this last summer including the PNW...

aha, that activity just picked up in the last half hour, i checked it like an hour or less ago and it was not showing the yellow warming up. i read it off the 3 charts, not just the first one. [link to www.haarp.alaska.edu]

that second one there has also gotten hotter in the last hour. i believe this is indicating tornadoes to come in the midwest, as this storm is moving northeastward and the lower 48 are having anomalous heat for the season right now. again.

[link to twitter.com (secure)] i'm trying to figure out how to read the numbers on pressure systems, to my uneducated eye this scenario is not looking good for the midwest and as i mentioned earlier, that blizzard to the great lakes by friday.
